UV weathering test chamber how to make the correct choice of light source and spray control
UV weathering tester is widely used for non-metallic materials, organic materials (such as: coatings, paints, rubber, plastics and their products) by the sun, humidity, temperature, condensation and other changes in climate conditions to test the degree of aging phenomenon of products and materials, in a short period of time to get discoloration, fading and other situations.ikxTextile Testing Instruments, Testing Equipment Manufacturer ikxTextile Testing Instruments, Testing Equipment Manufacturer UV weathering test chamber light source selection:ikxTextile Testing Instruments, Testing Equipment Manufacturer ikxTextile Testing Instruments, Testing Equipment Manufacturer 1, the light source using 8 UV series rated power of 40W ultraviolet fluorescent tubes for the light source, distributed on both sides of the machine, each side of 4;ikxTextile Testing Instruments, Testing Equipment Manufacturer ikxTextile Testing Instruments, Testing Equipment Manufacturer 2, UVB-313.UV-A340.UV-C365 light source for users to choose the configuration; (choose one)ikxTextile Testing Instruments, Testing Equipment Manufacturer ikxTextile Testing Instruments, Testing Equipment Manufacturer 3, UV-B313 lamp luminous spectrum energy is mainly concentrated in the 313m wavelength near;ikxTextile Testing Instruments, Testing Equipment Manufacturer ikxTextile Testing Instruments, Testing Equipment Manufacturer 4, UV-A340 lamp luminous spectrum energy is mainly concentrated in the 340nm wavelength near;ikxTextile Testing Instruments, Testing Equipment Manufacturer ikxTextile Testing Instruments, Testing Equipment Manufacturer 5, UV-C365 lamp luminous spectrum energy is mainly concentrated in the 365nm wavelength near;ikxTextile Testing Instruments, Testing Equipment Manufacturer ikxTextile Testing Instruments, Testing Equipment Manufacturer 6, because the fluorescent lamp light energy output will gradually decay over time, in order to reduce the impact of the test due to light energy decay, so the test chamber in all 8 lamps every 1/4 of the fluorescent lamp life, by a new lamp to replace an old lamp, so that the UV light source is always composed of new and old lamps, so as to get a constant output of light energy;ikxTextile Testing Instruments, Testing Equipment Manufacturer ikxTextile Testing Instruments, Testing Equipment Manufacturer UV weathering test chamber spraying control.ikxTextile Testing Instruments, Testing Equipment Manufacturer ikxTextile Testing Instruments, Testing Equipment Manufacturer 1, spray uniformity adjustment: use the controllers manual control function to observe the spraying condition in the open state, so as to adjust or replace the nozzle.ikxTextile Testing Instruments, Testing Equipment Manufacturer ikxTextile Testing Instruments, Testing Equipment Manufacturer 2, spraying state monitoring: the machine is equipped with a spraying device, spraying device simulates the temperature change and rain erosion when it rains, there are a number of nozzles, spraying evenly. When to spray, spraying how long, are set by the customer freely.ikxTextile Testing Instruments, Testing Equipment Manufacturer ikxTextile Testing Instruments, Testing Equipment Manufacturer 3、Users need to prepare deionized water with pressure.ikxTextile Testing Instruments, Testing Equipment Manufacturer ikxTextile Testing Instruments, Testing Equipment Manufacturer 4、Drainage: Drainage ditch is required on the floor near the host.ikxTextile Testing Instruments, Testing Equipment Manufacturer ikxTextile Testing Instruments, Testing Equipment Manufacturer 5、Working area: 234times;353cm (including personnel working space)ikxTextile Testing Instruments, Testing Equipment Manufacturer
